"Unfortunately, no. Not all darkroot grass can be successfully cultivated into darkblade grass. Even if it is successfully cultivated, the effect of darkblade grass is very unstable, and its offspring still cannot inherit everything of darkblade grass, and are basically not much different from darkroot grass."

"However, there are still subtle changes, and each improvement may result in slight changes. So I guess the magic plant should contain more special evolutionary laws - if each improvement uses the seeds of the latest generation of Dark Blade Grass, then I believe that as time goes by, it is only a matter of time before the Dark Blade Grass is completely consolidated as a new variety." Haipaster said seriously.

Hearing this, Rhett's pupils suddenly shrank. He was shocked and looked at Hepaster in a different light.

——He was really touched that such confidential information was shared with him without reservation.

"Such important news, are you just telling me like this? This is too selfless..." Rhett thought about it and couldn't help but say something.

"Haha, you, do you still think you are an ordinary person?" Hepaster shook his head and laughed, and asked back: "The talent you have shown in alchemy really makes me suspect that you are a monster, so I think it would be a blessing if the technology of magic plant improvement can be carried forward in your hands. After all, the research of this technology in the Ring Tower has really spent countless years and suffered a lot. If someone is willing to help, it would be great!"

So this was the idea... Rhett was stunned for a moment, feeling amused but also with a complicated expression on his face.

He first asked Manu in the simulation space: "Are you confident?"

After receiving a positive answer, he shrugged and said to Hepast, "Well, I have received such a great benefit, so I have to give something back. I will study this carefully after I go back. If I have any results in the future, I will come to you to discuss it."

"I look forward to that day." Hypast smiled and continued to purify the blood.

He watched the blood gradually thicken, his face suddenly became extremely solemn, and he said, "Rhett, I'm sorry I can't continue to communicate. The next step will be extremely critical, and I need to concentrate."

As soon as he finished speaking, Haipaster's mental power spread out like a tide, but if one sensed it carefully, one could find that this mental power was actually the spread of countless threads thinner than a hair, like countless tentacles spreading into the blood, performing fine manipulation. This required extremely amazing mental power quality and control ability to achieve this.

Rhett kept silent and watched carefully. After seeing Hypast's subsequent actions, he secretly estimated that he could also divide his mental power into such a scale. However, if he wanted to build on this and control it as precisely as Hypast and carry out each alchemical step in an orderly manner, it would require countless times of hard training and talent in alchemy.

He watched carefully, feeling the changes in the blood in the crucible. As time passed, the amount of blood in the crucible gradually decreased, but the blood power in it did not decrease at all.

Rhett narrowed his eyes slightly, everything in front of him was changing for the better.

If this trend continues, there is no doubt that we will be able to successfully refine the blood source power crystals in the end. This is a full year earlier than in the simulation!

After a while, the alchemy pot, which had not moved for a long time, once again spurted out streams of blood, which returned to the crucible and filled most of the gap.

And Hypaster once again sprinkled out a series of materials, which were almost the same as the first time, with the same types, only the control of quantity was different.

In Rhett's perception, the form of Hypastor's spiritual power changed again, from silk threads to multiple invisible hands, which stripped away the impurities in the blood and turned them into ashes in the flames, leaving only relatively pure blood power.

During this process, Leiter did see the power of a similar cycle.

As the blood rotates and rolls, under the multi-line control of mental power, it is somewhat similar to the blood circulation inside the human body. Through this technique, the efficiency of condensing blood source power is indeed greatly improved.

Time passes.

Four hours later.

All the alchemy pots are empty, all used up completely.

There was only half a pot of scarlet liquid left in the crucible. Rhett looked at the color and found it was very similar to the color of the red blood source bead.

Beads of sweat appeared on Hepaster's forehead. It was obvious that this was his first attempt and the pressure he was under was enormous.

Especially when it comes to the last step at this moment, the joy of success is about to come, the probability of failure cannot be ruled out, and the feeling in my heart can be described as ice and fire.

The flame under the crucible kept changing, but the overall temperature had risen a lot compared to the beginning.

Including the frequency of Hypast's mental power output, which is constantly adjusting and is also much more frequent than the initial state.

Hard work pays off. After another half an hour, the scarlet liquid in the crucible had shrunk into a fist-sized, hard, solid crystal. Under the burning flames, it could no longer change its shape.

It exudes a pure breath of blood power, and any extraordinary person can sense it even if it is in the air.

At this point, Hypast heaved a sigh of relief, wiped the sweat from his forehead with his sleeve, and stopped all the alchemical equipment.

“Hoo~Hoo~”

Hypast gasped, looked at the bloody coagulation in the crucible with complicated eyes, and was speechless for a long time.

Leiter swallowed, licked his lips, and asked expectantly, "Did it work?"

At this moment, he could feel the rich blood source energy in the blood-colored coagulation, and could hardly feel any impurities. If nothing unexpected happened, this was the blood essence stone mentioned in the simulation, which would be successfully refined in about a year! Hepaster picked up the blood-colored coagulation, held it in his hand and looked at it, hesitated for a moment, nodded, but shook his head and said:

"It's... a success, I guess. For a first experiment, this product is already quite successful."

"But it is still far from my ideal state. Originally, in my imagination, there should be no upper limit to the coagulation of blood source power. I can add as much as I want, and there is no restriction on impurities."

"But during the actual refining process, I discovered various problems that affected the formation of the blood source power crystal. In this experiment, I used the blood of 500 wind wolves, but this blood source power crystal only contained the blood source power of about 100 wind wolves. This shows that there are also problems with efficiency."

"Moreover, each time the purification process is performed, although it may seem that all the impurities have been removed, there are actually very faint residues that are the most difficult to remove. These residues accumulate into a large amount and are gathered in the crystal. This results in a limit on the amount that anyone can take. Depending on one's constitution, the upper limit of impurities that can be tolerated and the time required to digest the impurities will vary."

Lei Te was silent after hearing this. He was not pretending to be profound, but he really didn't understand...

But Manu in the simulation space also watched the whole process, thought for a while, and replied: "I can feel that the dark blade grass played a crucial role in this experiment. As an improved variety of the high-level magic plant dark root grass, it played a similar function as a medium in the process of separating blood source power and impurities, allowing the mental power to be separated smoothly. Otherwise, mental power alone, even at the sanctuary level, cannot directly touch the substance of blood source power, and must rely on special alchemical materials. Therefore, the addition of this dark blade grass is really clever. If the amount of dark blade grass is more, the efficiency should be able to increase."

"As for the problem of stubborn impurities, it is indeed a big problem. After all, blood is already dirty. It is theoretically difficult to remove all impurities without any error. What you think is perfect impurity removal may only be perfect under the current testing conditions, which is limited to imperfect standards. The actual situation is that there are still more subtle or special impurities that cannot be detected by the means. This requires hard work, raising the standards bit by bit, and slowly overcoming it."

As expected of a former scientific researcher, even though he has lost a lot of memory, his instinctive thinking can still keenly discover problems in the experiment and make analysis and evaluation.

Rhett thought about it for a while and then told Hypast the general content.

The latter stretched his waist, raised his head suddenly, and looked at Leiter with surprised eyes again. After a moment, he said with a wry smile: "I didn't expect you to find so many problems just by watching from the side!"

"In fact, I have noticed the amount of Dark Blade Grass that was added. If there were more, the efficiency could be increased by about 20%. But this is not enough. We need to think of other ways to make up for it."

"And the dark blade grass can't solve the problem of residual impurities. We also need to think of other solutions. Sigh."

Lei Te pretended to be in deep thought: "Thank you for your hard work. I will study it carefully when I get back..."

Hypast nodded tiredly, "Thank you very much, I hope you can surprise me again."

"Can you sell me the blueprint for this alchemical device?" Lei Te pointed at the alchemical pot on the ground and said, "With it, I can do experiments and verify my other ideas."

"Well, this alchemical device is indeed quite valuable. It was designed by the last president of the Golden Blood Academy, who was the most advanced Sanctuary alchemist on the continent at the time." Hypast was silent for a moment and said calmly.

"I know, so you can name any price you want." Rhett shrugged.

"Forget it. Talking about money hurts feelings. I was actually thinking that for an alchemy genius like you, who is embarking on the alchemy journey for the first time, I must give you a suitable gift." Hypast suddenly smiled: "Now I have decided, this is it. I will give you this blueprint and some finished products together - I hope the blood source power crystal will be perfected soon."

"Really? This gift is a little unexpected for me, but... it's quite a surprise!" Rhett spread his hands and exclaimed.

"Take it. I hope it brings you good luck and inspiration." An old yellowed drawing appeared out of thin air in Hepaster's hand and he handed it to Rhett.

"Thank you." Rhett thanked him solemnly, took it with both hands, glanced at it, and put it into the space equipment.

Then, Hepast tidied up the table a little and invited Rhett to go back next door to have some tea and relax.

After discussing some issues regarding alchemy experiments, Lei Te took the initiative to ask, "By the way, it seems like I haven't heard from Black Star for a long time. How is he doing recently?"

"You mean Black Star? When they were fighting against the orcs, all countries were very strict in cracking down on evil forces, and not many evil people dared to show up at that time. So, Black Star was bored, so he went to the Strange Rock Volcano with Jinsha, saying it was for training." After relaxing, Hepast said comfortably: "I heard that Black Star was injured and didn't want to come back. Black Star is too stubborn, like a child who will never grow up..."

"What's his actual age?" Rhett asked with interest.

"She should be under 30, which is actually quite young." Hypast said, "By the way, I have already selected the candidates for the alchemy construction team I promised you. Do you want to meet them?"

Lei Te hesitated for a moment and said, "No need. I trust the people you sent. When will they arrive?"

"Within a week, probably. They are not only alchemists, but also powerful great mages and sky knights. It won't take too long."

Lei Te nodded and sipped the tea.

After continuing to chat with Hepast for half an hour, he found an excuse to leave.

A man walked up a few flights of stairs and came to the lobby on the first floor, where he saw his youngest son, Thales.

"Hey, Father, here!"

Taylors was sitting in a triangular chair near the window. When he saw a familiar figure coming down the stairs, his eyes lit up and he waved to say hello.

"Long time no see, Taylor, how are you adapting here?"

Rhett walked up and ruffled Taylor's hair, smiling.

"It's great. The alchemical atmosphere here is quite strong. Everyone is very enthusiastic. Almost all the questions we don't understand can be answered here." Thales said with a hint of excitement on his face.

"Oh? It seems that you like it here very much. How about staying here?" Rhett raised his eyebrows and asked back.

"Ah? Forget it." Thales said listlessly, "Compared to here, I want to go home more - I can still study alchemy at home and enjoy the company of my family. I haven't seen Mina and Abel for a long time, I really hope to meet again as soon as possible."

"That's good, this wish will come true soon."

Rhett patted Thales on the shoulder, turned and walked out of the gate of the ring tower.

Thales' eyes lit up, he greeted his companions not far away, and quickly followed.

Arriving at the flat ground outside the tower, Thales looked excited. He was ready to be wrapped in elements by his father, and left quickly.

However, the imagined scene did not appear, and my father kept moving forward towards the outskirts of the forest.

Thales quickly followed his father's footsteps and asked curiously from behind, "Father, where are we going?"

"Let's go to the Ring Market for a while longer." Lei Te said without turning his head, and the scene of Vina's House unconsciously appeared in his mind...
